Wow! For a first exploit, it's not bad, it may even be the fastest Exploit ever!

Though it's breaking my SMS disc that lead me to try and load Homebrew/ISO, so I don't have any working physical copy of SMS (I don't want to pay the silly price asked for used copies which is currently twice the price I bought mine brand new!), my disc doesn't get past Nintendo logo, it then shows a Disc error message. I'll give it a try anyways, but i don't expect it to work.

Something bugs me, sometimes games just boot into 60Hz mode, hope it's something that lays in the specific game's save.

The disc error messages are vulnerable too fwiw, but all I was able to do was replace them with my own text, so it wouldn’t get you very far… Have you tried booting up your disc with different system languages? It sounds like the error happens because of the 60Hz mode prompt, maybe the French file is corrupted but another language might work?

Speaking of 60Hz mode, I’m not sure where the setting’s stored (not in the save anyway) but once you set the game into 50Hz it never asks you again unless you boot up the game while holding B.

So, my SMS disc is too destroyed, it stalls to Nintendo Logo (but no error message), tried every language possible to no avail.

Seems that 480i mode in NTSC games doesn't update the setting in the console SRAM (only tested with Crazy Taxi), so if you play those games you won't have to set the console back to 50Hz. Didn't test with the progressive option though. Forcing Pal games to 60Hz with SWISS seems to set it in the console too (unless there are exceptions, I only tested that with SMS and SMKDD).

Hey there, I have both JDM and US gamecubes (though I do believe they are internally the same besides jumper configuration) I also happen to have a PAL copy of Super mario sunshine somewhere but there not chipped, I can boot it with a freeloader but not sure if they will force any kind of resolution changing or what not so probably not going to be a valid result but i can give it a go if youd like to know what happens.
